In Decky Display Settings → Picture, select render resolution and maximum refresh rate. This example uses a 2960 × 1848 panel: Native uses its pixels. Higher resolutions and rates require compatible hardware; 60 Hz is a requested maximum, not a measured rate.
Step by step
- On the device, open Decky Display Settings → Picture. Resolution chooses Native, a smaller size or Automatic. Refresh rate chooses the rate the device asks for.
- On the Mac, use the device’s display controls or Settings → Devices for its picture settings. Use Scaling to choose how much desktop fits on that screen.
- Choose a larger-looking desktop for easier reading, or more desktop space for extra windows. Lower the resolution or refresh rate if the device struggles.
- On the device, open Decky Display Settings → Picture. Resolution chooses Native, a smaller size or Automatic. Refresh rate chooses the rate the device asks for.
- On the PC, open Decky’s Settings → Devices for that device’s Maximum resolution and Maximum refresh rate. To change text size, open Settings → Screens → Arrange displays in Windows Settings and set Scale for the Decky display.
- Choose a larger scale for easier reading, or a smaller one for more desktop space. Lower the resolution or refresh rate if the device struggles.
What to know
Native uses the panel’s pixels. HiDPI draws a smaller logical desktop with more detail. Intermediate scaling can render above panel resolution and scale down, which adds Mac work. Higher rates depend on the panel, the Mac and the connection; a selected maximum is not a measured frame rate.
Windows scales Decky displays like any other monitor. Higher rates depend on the panel, the PC’s graphics hardware and the connection; a selected maximum is not a measured frame rate. Portrait needs Extend.
If it does not work
Try a lower resolution and 30 Hz before changing several options together. Use H.264 if the device has trouble with H.265.
